The objects of th ADJUSTABLE GUIDEWAY;

a division of my prior 428,405, filed Decemis invention are to provideimproved means for easily and efiectively taking up wear on theguideways for the sliding head of a power press; to employ for thispurpose a gib movable transversely of itself toward and away from theslidlng member of the press and having a beveled outer edge, togetherwith means for adjustably exerting pressure to exert such pressure onsaid beveled edge; by means of members or dogs which at one end engagesaid beveled edge and at the other end have a fixed seat,

together with means for clamping said gibengaging end toward the housing0 to obtain other advantages and press, and

results as may be br ing description.

Referring to the f the ought out in the followaccompanying drawings,

in which like numerals of reference indicate the same parts throughoutthe several views,

Figure 1 is a press embodying my 2 is a horizontal cross-section of line2-2 Figure the power press on ing downward.

In said drawings front elevation of a power improvements, and

of Fig. 1, lookhave shown my improvements embodied in a power press ofcommon and well-known type, having a frame with side pieces or bed 2 anda top-leaf 3;

side pieces and topeccentric portions 5, by pitmen 6, 6, to a hammerreciprocate toward 2 between the side pieces 1.

is shown having a one end of itself, 0 press, provided to cause siredeven though continuously. This housings 1, 1, a ournalcd in said leaf isa shaft 4 having 5, which are connected 7, adapted to and away from thebed 1. The shaft 4 driving pulley 8 upon utside the frame of the and anyusual clutch means 81 is the press to operate as the driving pulleyrotates press is shown only for purposes of illustration, it beingunderstood that my improvements to be described as applied ous otherconstructions and I to be understood as respect.

to it can be applied to presses of varido not wish limiting myself inthat The hammer 7 is guided in its up and down movements by guideways onpleces 1, 1, and in carrying out the sidemy invention I preferablyprovide each side-piece with a fixed gib 9 at one s1 de of a projection10 on ember 4, 1920, Seria1 No. 428,405. Divided and this applicationfiled August 26, 1924. Serial No. 734,185. I

the hammer, see Figure 2, and an adjustable gib 11 at the other side ofsaid projection. This adjustable gib I have shown capable of slidingslightly upon the face 21 of the sideiece or housing 1 toward theprojection 10 and held to said face 21 by bolts 12 which can be loosenedto facilitate such sliding or tightened to resist it. I have shown suchbolts as threaded into the gib and extending loosely through theside-piece 1 to permit the movement, but other constructions could. beemployed. The edge of the adjustable gi 11 away from the projection 10is beveled or sloping, as at 13, and engaged by the correspondinglybeveled ends of dogs 14 which lie substantially parallel to the face 21of the side-piece or housing and are provided at their ends away fromthe adjustable gib 11 each with a. foot 15 which turns toward the faceof the housing and enters a seat 16 therein to prevent movement of thedog away from the gib. A bolt 17 extends through each dog intermediateits ends and into the face 21 of the housing 1, so that upon tighteningthese bolts the ends of the dogs engaging the adjustable gib will forcethe same toward the projection 10 on the hammer and so take up loosenessfrom wear or the like.

In order to lock the adjusting bolts 17 against inadvertent movement, apassage 18 is drilled in the housing 1 for each bolt transverse to thesame, and a clamping screw 20 mounted in each passage, preferably with aloose pin 19 between its inner end and the bolt. I have shown the bolts17 as screwing into tapped holes in the housings, and with thatconstruction the pins 1.9 have their ends away from the clamping screwscorrespondingly shaped so as to fit against the threaded sides of thebolts without damaging the threads. Thus to efiect adjustment of themovable gib 11, the clamping screws 20 are slackened. the bolts 12loosened and the clamping bolts 17 tightened until the adjustable gib isclose against the projection 10 on the hammer; then the bolts 12 andclamping ing from the spirit and scope of the invention, and I do notwish to be understood as restricting myself except as required by thefollowing claims when construed in the light of the prior art.

Having thus described the invention what- I claim is:

1. The combination and housing therefor, ing atone side of said abletoward and away the face'ofthe housing and having a beveled surface atits outer edge, and means upon said face of the housing for adjustablyexerting pressure toward said face upon said beveled surface.

2. The combination with a sliding member and housing therefor, of a gibon said housing at one side of said sliding member movable toward and.away from the same and having its outer edge beveled, a member engagingat one end said beveled edge and at its other end a seat on the housing,and means for clamping said gib engaging end toward the housing.

3. The combination with a sliding memher and housing therefor, of a gibon said housing at one side of said sliding member movable toward andaway from the same and having its outer edge beveled, an angular dogengaging'at one end said beveled edge and at its other end a seat on thehouswith a sliding member of'a gib on said houssliding member movfromthe same upon ing, and means for clamping said dog toward the housing.

4. The combination with a sliding mem her and housing therefor, of a gibon said housing movable transversely of itself and having an edgeadapted to guide said member and a beveled or inclined outer oppositeedge, an angular dog en aging at one end said beveled or inclined e goand at its other end a seat on the housing, means for clamping said dogtoward the housing, and means forelamping the gib to the housing.

5. The combination with a sliding member and housing therefor, of a gibon said housing movable transversely of itself and having an edgeadapted to guide said member and a beveled or inclined outer oppositeedge, an angular dog engaging at one end said beveled edge and at itsother end a seat on the housing, and a bolt extending loosely throughthe dog and into the housing.

6. The combination with a sliding head having a lateral projection, of ahousing having gibs providing between themselves a slideway for saidprojection, being movable transversely of itself toward and away fromthe projection and having its. edge away from said projection beveled orinclined, a dog having'one end portion substantially parallel to thesaid housin and spaced therefrom and engaging the sai beveled edge ofthe movable gib and its other end housing to resist movement away fromsaid movable gib, and means for clamping said gib-engaging end portionof said dog toward said housing.

7. The combination ber and housing therefor, of a gib on said housingmovable transversely of itself and having an edge adapted to guide saidmember and a beveled or inclined outer opposite edge, an angulardogengaging at one end said beveled edge, a bolt extending looselythrough the dog and threaded into the housing, aslidingpin transverse tothe threaded end of the bolt with its end shaped to fit -the thread, anda clamping screw for forcing'said pin against the bolt.
